+ * Largely frivolous way to define all my command-line options. I
+ * present here a parametric macro which declares a series of
+ * _logical_ option identifiers, and for each one declares zero or
+ * more short option characters and zero or more long option
+ * words. Then I repeatedly invoke that macro with its arguments
+ * defined to be various other macros, which allows me to
+ * variously:
+ *
+ * - define an enum allocating a distinct integer value to each
+ * logical option id
+ * - define a string consisting of precisely all the short option
+ * characters
+ * - define a string array consisting of all the long option
+ * strings
+ * - define (with help from auxiliary enums) integer arrays
+ * parallel to both of the above giving the logical option id
+ * for each physical short and long option
+ * - define an array indexed by logical option id indicating
+ * whether the option in question takes a value
+ * - define a function which prints out brief online help for all
+ * the options.
+ *
+ * It's not at all clear to me that this trickery is actually
+ * particularly _efficient_ - it still, after all, requires going
+ * linearly through the option list at run time and doing a
+ * strcmp, whereas in an ideal world I'd have liked the lists of
+ * long and short options to be pre-sorted so that a binary search
+ * or some other more efficient lookup was possible. (Not that
+ * asymptotic algorithmic complexity is remotely vital in option
+ * parsing, but if I were doing this in, say, Lisp or something
+ * with an equivalently powerful preprocessor then once I'd had
+ * the idea of preparing the option-parsing data structures at
+ * compile time I would probably have made the effort to prepare
+ * them _properly_. I could have Perl generate me a source file
+ * from some sort of description, I suppose, but that would seem
+ * like overkill. And in any case, it's more of a challenge to
+ * achieve as much as possible by cunning use of cpp and enum than
+ * to just write some sensible and logical code in a Turing-
+ * complete language. I said it was largely frivolous :-)
+ *
+ * This approach does have the virtue that it brings together the
+ * option ids, option spellings and help text into a single
+ * combined list and defines them all in exactly one place. If I
+ * want to add a new option, or a new spelling for an option, I
+ * only have to modify the main OPTHELP macro below and then add
+ * code to process the new logical id.
+ *
+ * (Though, really, even that isn't ideal, since it still involves
+ * modifying the source file in more than one place. In a
+ * _properly_ ideal world, I'd be able to interleave the option
+ * definitions with the code fragments that process them. And then
+ * not bother defining logical identifiers for them at all - those
+ * would be automatically generated, since I wouldn't have any
+ * need to specify them manually in another part of the code.)
